GRAIN-OAR DOOR.

SPECIFICATION forming part of Letters Patent No. 709,325, dated September 16,1902. Application tiled MayZ, 1902. Serial No. 105,624. (No model.)

T a/ZZ whom, it may concern:

Be it known that I, ALONZO LEVI HOOK, acitizen of the United States, and a residentof Coffeyville, in the county of Montgomery and p State of Kansas, have invented certain new and usefullmprovements in Grain-Oar Doors,

of which the following is a specification.

My invention relates to doors for graincars, and it appertains to doors of this char- 1o acterheld in slideways "and adapted t-o be lifted therein with suitable mechanism supported` above the door and also adapted to be raised abovethe slideways and swung upto the top of the car, where it may be supported by a hook or other device, all as is common z5 specification, and in which- Figurel is a View showing a section of a car with the door lowered and fastened as in use. Fig. 2 is an interior view of the same. Fig. 3 is a section on line wof Fig. 2. Fig.

3o 4 is an enlarged detail view showing the lever-and-ratchetmechanism, and Fig. 5 is a perspective view showingthe slideway and shaft-supporting bracket of one side of the door.

I am aware that a door for grain-cars consisting of two parts hinged together is not broadly new, andI am also aware that various means have been employed for lifting the door and alsothat such doors have been 4o arranged to slide in guideways.

What I claim as my invention is the new and improved grainLdoor for cars, which I will now'proceed to describe in det-ail as follows: k

In carrying out my invention I employ a door A, having hinged toits upper edge a reduced door B. D indicates castings secured to the'inner side of the car-framing or stanchiens, forming side members of the doorp. 5o opening.4 The castings Dare formed with guideways E in length about equal with the width ofthe door A and in which the door is adapted to slide. The side edges of the doors A and B are protected with metal strip A. (See Fig. 2.) F indicates brackets projecting from the castings G, which latter, with the castings D, extend the whole length of the stanchions above mentioned and are secured thereto by screws, bolts, or other suitable means. The castings D and G at both sides 6o of the door are tongue-andgrooved together. (See Fig. 5.) With sideY castings formed in two parts it is apparent the upper casting, carrying the brackets F, may be adjusted to provide support for the shaft H at varying heights. Advantage is had in fitting the abutting ends of the said castings D and G together by a tongue-and-groove joint, since should it become necessary to adjust one or both of the castings G for setting the shaft- 7o supporting brackets F in alinement or to. slight elevated position adapted for lproper support of the shaft H the said adjustment of the upper casting may be made and still leave the stanchions with a substantially unbroken metal facing-that is, should the adjustment described not carry the lower end of the tongue on the casting G out of the groove orsocket in the upper end of the casting D.

`The brackets F provide support for the shaft H, arranged above the door-opening in the car and on the inside thereof, as shown. One end of the shaft H outside the bucket is provided with a head I, and onthe other end 85 of said shaft I arrange a toothed or ratchet wheel J, straddled by the forked members of a lever K. Between the said forked members is pivoted a weighted dog L, with its shorter end engaging the teeth of the ratchet-wheel 9o J. Above the said ratchet-wheel J and secured to the side of the car I arrange a pawl M, having engagement therewith to prevent reverse rotation of the ratchet-wheel. From the shaft H depend chains whose lower ends connect loops or eyes at the upper edge of the door A. (See Figs. l and 2.) On the outside of the door A, I arrange sliding bolts N,

adapted for engagement with recesses in the stanchions or side members of the door.

The loo.

- that in use withy a car loaded with grain and both doors secured When it is desired to unload the car the hooks P are first disengaged, when the hinged door may be turned inwardly. With the door B turned as stated an unloaderlmay enter the car and by Working the lever K wind the doorelevating chains on the shaft H. The lower end of the said chains being fast to the upper edge of the door A, it is apparent that the latter may be raised in the guideways by working the lever, as stated above, and that with the doors raised grain will pass out through the opening provided fast orslowly, according to the elevation of the lower door in the guideways. When a car is unloaded, the door may be raised until free ot' its guideways and then swung inwardly up to the top or roof of the car and be secured in such position by a hook or other desired means.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination With a car-door adapted to be elevated, means for guiding the door and manually-operated means adapted to be Worked for elevating the door, of peculiar gudeways for the door and peculiar support for the said elevating means, the said guideways consisting of castings having in addition to means for guiding the door, a groove or socket at their upper ends, and the support for the elevating means consisting of castings having a tongue at their lower'ends adapted to enter and fit a socket at the upper end of the lower casting and integral brackets providing support for the Windingshaft, chains leading therefrom with xed connection to the door and also the means for working said shaft, a ratchet-Wheel on the shaft, a lever having pivotal movement on the shaft and carrying a weighted dog having slipping movement from tooth to tooth of the y ratchet-Wheel, and a fixed pawl operating to hold the shaft as wound, substantially as described.
